Is there an official classification?
Hungary has no office classification set by law or by a standard. Classes A, B and C are the market's own terms, used by owners, developers and advisory firms, so a building's class is always its advertiser's or adviser's own assessment.
The Budapest Research Forum (BRF) publishes the Budapest office market's figures every quarter. Within the modern office stock it records Class A and Class B speculative office space. According to its report for the third quarter of 2026, two thirds of the speculative stock is Class A and one third Class B. BRF does not report a Class C. The latest figures are on the Budapest office market page.
As an international reference, people often quote BOMA International, the North American association of office building owners and managers. In its description, Class A buildings compete for premier tenants, with rents above the area's average, high-quality finishes and state-of-the-art systems. Class B buildings serve a wide range of tenants, with average rents and adequate systems. Class C buildings offer functional space at rents below the average. BOMA stresses that a class is always relative to its local market.
What makes a Class A office building
From a Class A office building you can usually expect:
- Age: a new or thoroughly refurbished building.
- Building systems: four-pipe fan coils or equivalent heating and cooling, temperature control room by room, mechanical fresh air.
- Layout: raised floors for cabling, suspended ceilings, large floors that can be divided and a column grid that allows a flexible layout.
- Services: a reception, access control, fast lifts, underground parking, often bicycle storage and showers.
- Certification: many buildings hold BREEAM, LEED or WELL certification. You will find them among the ESG office buildings too.
- Location: usually in an office district with good public transport.
What a Class B office means
Class B office buildings are simpler. They include older office buildings, former industrial and retail buildings converted into offices, and buildings whose systems or services fall short of Class A.
A Class B building often has no raised floor or underground car park, cooling by split air conditioning room by room, and a more modest reception and shared services. Class B does not mean poor quality: many well-located, refurbished buildings belong here. Rents are lower, and many owners also let small, self-contained offices.
Class C offices
Class C usually refers to older buildings, unrefurbished or only partly refurbished, where offices come with basic fittings: offices in old residential blocks, for example, or plain office buildings with no services. Their rents are the lowest, but check the heating and cooling, the parking and step-free access with particular care. If you are after an office in a flat, look at the flat offices.
The classes side by side
| Class A | Class B | Class C | |
|---|---|---|---|
| Age | new or refurbished | older or simpler | old, unrefurbished |
| Heating and cooling | central, controlled room by room | central or split units | individual solutions |
| Layout | raised floors, large divisible floors | simpler, smaller units | as built |
| Services | reception, access control, underground parking | the basics | few or none |
| Certification | common (BREEAM, LEED, WELL) | rare | usually none |
| Rent | highest | mid-range | lowest |
The market rents published by the advisory firms are collected on the Budapest office market page; each building's own rent is on its page.
Beyond the class
As there is no official standard, two Class A buildings can differ a lot. "A+" or "premium" is the advertiser's own label. So do not rely on the class alone: ask for the technical specification, and on the viewing look at the building systems, the lifts, the shared areas and the parking. What else to compare is in our guide to comparing office buildings.
Searching by class on Officerentinfo.hu
On Officerentinfo.hu, Class A and Class B offices have their own lists, and you can filter the search by class. Most buildings are advertised by their owner or developer, so offers come directly from the owners. If you have no time to go through them all, describe the office you are looking for and the landlords of suitable buildings will send you offers.
